UK Prime Minister Tony Blair urged India and Pakistan to show calm and restraint as he arrived in the Bangladeshi capital of Dhaka at the start of a week-long trip to South Asia.

Mr Blair told journalists travelling with him that he and US president George Bush had discussed at length the crisis over Kashmir which had brought nuclear powers India and Pakistan to the brink of war.

He said he had no blueprint for peace in Kashmir, but added that he and Mr Bush believed it a "very serious issue with potentially far reaching and damaging consequences if the tension gets out of hand".

"The most important thing is to try to exert as strong a calming influence as possible on a situation that is obviously potentially very serious in its consequences for the stability of the region, and of the wider world," Mr Blair said.

"I can't solve the Kashmir problem just by going to India and Pakistan. But I hope by putting views on behalf of everybody in the international community, we can have a calming influence," he added.

Peacekeeping role

He said that the Bangladesh leg of his trip was important on two main counts.

The first was to see how the aid programme - the UK's second biggest - was being spent.

The second was to see if Bangladesh might play a part in the peacekeeping plans for Afghanistan.

The visit comes as fresh violence in Kashmir threatens to derail diplomatic moves to ease military tensions between the two countries.

One policeman was killed and more than 20 other people were injured on Wednesday in grenade attacks near the state assembly in the Kashmir summer capital Srinagar, police there said.

There has also been more violence at the Line of Control between the countries in Kashmir with six Pakistani soldiers reported killed.
